WATCH-CASE CENTER AND P ENDANT.

SPECIFICATION forming part of Letters Patent No. 360,478, dated April 5,1887.

Application filed July 31, 1886. Renewed March 1,1887. Serial No.229.376. (No model.)

To allwhoml it may concern.-

Be it known that I, ALBERT H. POTTER, of Geneva, in the Republic ofSwitzerland, have invented certain new and useful Improvements inWatch-Case's; and I do hereby declare that the following is a full,clear, and eXact description thereof, reference being had to theaccompanying drawings, in which Fign re 1 is a perspective view of theparts of my case-center and'pendant separated from Fig. 2 is a like viewof the same united, and Figs. 3 and 4 are sections upon line a: a: and zz, respectively, of Fig. 2.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to furnish a simple, inexpensive, andefficient means whereby a watch-case pendant may be at- .tached to acase-center; and to this end said invention consists, as an improvementin watch-cases, in a case-center provided with a radial rectangularopening, in combination with a pendant which has its inner end fittedinto and through such opening and headed down upon the inside of saidcase-center, substantially as and for the purpose hereinafter specified.

In the carrying of my invention into practice I providewithin'acase-center, A, a radial opening, a, which is rectangular inshape, and is preferably arranged with its longest axis in a line withthe plane of said case-center. Combined therewith is a pendant, B, ofany usual form, that is provided at its inner end with a tenon, b, whichcorresponds transversely to the size and shape of said opening, andterminates in two shoulders, I), that conform to the curvature of theperiphery of said case-center. The tenon 2), thus shaped, is placedwithin the opening or mortise a, and its projecting end or oppositesides of the same headed down with a hammer or other suitable tool, bywhich means the pendant and case-center are firmly united and not liableto separation. If desired, said tenon and the sides of said mortise maybe covered with solder, and after said parts have been united,

as described, sufficient heat may be applied to melt the solder; but itis believed that such additional strength will not be needed, as theprincipal strain upon said pendant will be torsional, and such will beeffectually met by the rectangular form of its tenon and of the mortise.

Having thus described my invention, what I claim is-- As an improvementin watch-cases, a casecenter provided with a radial rectangular opening,in combination with a pendant which has its inner end fitted into andthrough such opening and headed down upon the inside of saidcase-center, substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this3ist day of July, A. D. 1886.

. ALBERT l-I. POTTER.
